RATCHET-WRENCl-l.

SPECIFICATION forming part of Letters Patent No. 582,013, dated May `4,1897.

Application filed September 14, 1896. Serial No. 605,732. (No model.)

To all whom, t may concern.:

Be it known that I, JOHN ELLEBREGHT, of the city of St. Louis, State ofMissouri, have invented certain new and useful Improvements inRatchet-Wrenches of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to ratchet-wrenches; and it consists in the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

The object of my invention is to operate nuts Without removing thewrench during such operation and in positions Where the handle of thewrench cannot make a complete circuit.

Figure 1 is a view in elevation of my improved ratchet-wrench. Fig. 2 isa bottom plan view of the Wrench shown in Fig. 1. Fig. 3 is a horizontalsectional view taken approximately on the line 3 3 of Fig. 1. Fig. 4 isa transverse sectional view taken approximately on the line 4 4 of Fig.3. Fig. 5 is a vertical sectional. view taken approximately on the line5 5 of Fig. 1.

In the construction of my improved ratchet- Wrench I employ the handle6, in the front .end of which is formed a circular opening 7,

which opening serves as a bearing for the rotating head S. An opening 9is formed in the handle 6 and intersects the opening 7. A smalleropening 10 extends from the end of the opening 9 a short distance, and acatch 11 is placed in the opening 9 with its point 12 projecting intothe opening 7. The head 13 of the catch is reduced in size and extendsinto the opening 10, which opening forms a bearing for said head, and acoil-spring 14 is placed upon said head with one end resting against theshoulder 15, formed by the junction of the head 13 with the body of thecatch, and with its opposite end resting against the shoulder 16, formedat the junction ot the openings 9 and 10.

An elongated slot 17 isl formed in the handle 6 and intersects theopening 9, and a pin 18 is fixed in the catch 11 and operates in saidslot 17.

The rotating head 8 is formed integral With the circular opening audupon the end of the circular block 19, and a recess 20 is formed in thelower end ot the block 19 and is designed to receive the nuts which areto be operated.

Formed in the periphery of the rotating head 8 are square or rectangularnotches 21, designed to receive the point 12 of the catch 11. The point12 has a bevel-face on one of its sides, and the parts are arranged insuch a Way that when the handle is operated in one direction the head 8will be rotated, and when the handle is operated in the other directionthe catch 1l will slip from notch to notch and the head 8 will not berotated.

Assuming that the parts of the Wrench are arranged for the purpose oftightening nuts, the arrangement may be changed whenit is desired toloosen nuts by manually engaging the pin 18 and operating the catch 11until the point 12 is out of engagement with the notches in the rotatinghead, then removing the handle from the head and turning said handleover and replacing it upon the head.

The catch 11 forms a ratchet connection between the handle 6 and therotating head S, and the ratchet is reversed simply by' removing thehead from the handle and turning the handle over.

rPhe side Walls of the notches 2l perform the functions ofratchet-teeth, and in order to make the ratchet reversible it isnecessary to make these side walls substantially parallel with eachother and on radial lines relative to the center of the rotating head.It is to this reversible ratchet and to the construction whereby it ismade reversible that I Wish to call especial attention.

I claim- In a ratchet-Wrench, the handle 6 having 7 in its front end andthe opening 9 intersecting said opening 7 and the opening l0 extendingfrom the inner end of said opening 9 and the opening 17 intersectingsaid opening 9, the rotating head 8 removably operating in said opening7 and having the rectangular notches 21 formed in its periphery, theblock 19 formed integral with one end of said head and having thepolygonal recess formed in its lower end to receive the nut, the catch11, having the bev- IOO eled point, slidingly mounted in said openingthe body of said catch l1 and operating in ro 9 and having its headreduced in size and eX- said slot 17, substantially as specified.tending into said opening 10, the coil-spring In testimony whereof Iaffix my signature 14: placed upon said head With one end restinpresence of two Witnesses.
